Abstract

The invention provides a device and system used for forming vascular embolism and application of the device and the system. The device is a 'sandwich' structure penetrated by a guidance guide wire and comprises the guidance guide wire, a first half balloon body, a second half balloon body, a sponge body and a pushing rod. The head end and the tail end are defined for the guidance guide wire; a first half balloon inner cavity is formed in the center of the first half balloon body, and the first half balloon body is arranged on the guidance guide wire in a sleeved mode through the first half balloon inner cavity; a second half balloon inner cavity is formed in the center of the second half balloon body, and the second half balloon body is arranged on the guidance guide wire in a sleeved mode through the second half balloon inner cavity; the sponge body is arranged between the first half balloon body and the second half balloon body, and the guidance guide wire penetrates through the sponge body; the pushing rod and the second half balloon body are connected into a whole. The device can effectively embolize the blood vessel and accurately control the embolism level.
